    + Remove cluster query

    + Prometheus adapter tests

Make sure we override the method from CE, too

* adds basic discussions API for issues, snippets and epics
* adds notes API endpoint to epics
* reorganizes notes specs (so same tests can be used for all noteable types - issues, MRs, snippets, epics)

Unify deployment_platform interface with CE

See merge request gitlab-org/gitlab-ee!4875

Make sure we override the method from CE, too

This name already existed in EE, so we rename the CE version to make them
distinct.

Make --prune a configurable parameter in fetching a git remote

See merge request gitlab-org/gitlab-ee!4818

Removes confusing/unnecessary checkboxes when trying to configure an
integration. If there is only one supported event we don't need to
allow these to be individually disabled since the integration can be
disabled instead.

E.g. Project Integrations for GitHub, Bugzilla, Asana, Pipeline emails and Gemnasium

Allows us to hide the Triggers checkboxes on the GithubService form

API URL also determined from GitHub project URL
